Method for performing derivative scenario in game program

Abstract

Disclosed is a method for performing a derivative scenario in a game program operated on a home television game machine, has the steps of: generating the derivative scenario on the basis of a step in the game program; and performing the derivative scenario on the basis of real time proceeded by a first timer means with which a main body or an external storage device of the home television game machine is provided; wherein the derivative scenario is defined to be performed in the process of a relative time and the relative time is related to the real time so that the derivative scenario is performed in the process of the real time.

What is claimed is: 
     
       1. A method for performing a derivative scenario in a game program operated on a home television game machine, comprising the steps of: generating said derivative scenario on a basis of a step in said game program, said derivative scenario having a situation in which an item changes to provide one of at least two different results in accordance with process of real time; and   performing said derivative scenario on a basis of said real time proceeded by a real time clock,   wherein said derivative scenario is defined to be performed in process of relative time, and said relative time is related to said real time, so that said derivative scenario is performed in process of said real time to exhibit said one of at least two different results in accordance with real time-based change of said item.   
     
     
       2. The method according to claim 1, wherein: said relative time is started and converted into said real time when said derivative scenario is generated.   
     
     
       3. The method according to claim 1, wherein: said derivative scenario is generated when said game program proceeds to said step.   
     
     
       4. The method according to claim 3, wherein: said proceeding to said step is given by a key operation of said player.
